A Dumb Policy on Nuclear Weapons: Does It Matter?

Today President Obama announced a new strategic policy with regard to the use of nuclear weapons. The New York Times reports:

President Obama said Monday that he was revamping American nuclear strategy to substantially narrow the conditions under which the United States would use nuclear weapons. … To set an example, the new strategy renounces the development of any new nuclear weapons, overruling the initial position of his own defense secretary. …
For the first time, the United States is explicitly committing not to use nuclear weapons against nonnuclear states that are in compliance with the Nuclear Nonproliferation Treaty, even if they attacked the United States with biological or chemical weapons or launched a crippling cyberattack.

On its face, that is unbelievably stupid. A country attacks us with biological weapons, and we stay our hand because they are “in compliance with the Nuclear Nonproliferation Treaty”? That is too dumb even for Barack Obama. The administration hedged its commitment with qualifications suggesting that if there actually were a successful biological or chemical attack, it would rethink its position. The Times puts its finger on what is wrong with the administration’s announcement:

It eliminates much of the ambiguity that has deliberately existed in American nuclear policy since the opening days of the cold war.

That’s exactly right. The cardinal rule, when it comes to nuclear weapons, is keep ’em guessing. We want our enemies to believe that we may well be crazy enough to vaporize them, given sufficient provocation; one just can’t tell. There is a reason why that ambiguity has been the American government’s policy for more than 50 years. Obama cheerfully tosses overboard the strategic consensus of two generations.
Or pretends to, anyway. Does anyone doubt that the administration would use nukes in a heartbeat if it considered such measures necessary? I don’t. The problem is that when the time comes to actually use nuclear weapons, it is too late. The danger here is not that the Obama administration has really gone pacifist. On the contrary, the significance of today’s announcement appears to be entirely symbolic–just one more chance to preen. The problem is that our enemies understand symbolism and maybe take it too seriously. To them, today’s announcement is another sign that our government has gone soft, and one more inducement to undertake aggressive action against the United States.
